Router/Modem issue?

Back when i first got Comcast internet, i had setup my account to have a static IP adress. All was well. I had a surfboard modem and a belkin 4 port router. The router runs off the WAN port than splits the connection off to my dads pc (XP) and my pc (XP).

About two months into having the connection, with no probs, lightning zapped my modem and my router. I replaced the router with the exact same model, and comcast issued me a RCA modem that i didnt want.

For good measure i replaced all the Cat5 cables and ethernet cards so it was all new and fresh. About 3 days later the problem began. 4 or 5 times a day, sometimes alot more, sometimes alot less, the internet cuts out.

The connection from the router shows active and well, yadda yadda. No internet. So i go over to the modem and router, and pull the power from both. Plug them back in and everything is cool.

Around the same time i got the new modem comcast started giving my dynamic ip's, and i think thats the problem. It seems almost like the modem doesnt renew, and the router gets locked up.

Well a tech comes out, oh boy, and gives me a new surfboard modem. Hey, i like this guy! He says he thinks the problem is the ip, and says to give it a few days and see what happens.

Three hours later, BAM! Locked up. This time i notice something, though. I cant log into my router. When i try to go to it (192.168.2.1) it never does anything but say cant be found.

Reset the power, bammo its all good. What i am wondering is if it could be the way my router is setup? Its set as dynamic, and uses DHCP. Ive tried it 100 different ways to no avail.

The only thing i havent tried is running the modem off the uplink port of the router, think that would help? Its important to note that comcast refuses to accept its their problem, and kindly tells me they dont offer static ip addy's anymore.....which i think its BS.

After 4 months of this im tired, and i need help. Ive been through another router also, just incase i got a defective. I'm positive its not fault of equippment.

Well that indicates a definite problem somewhere between your computer and the router. That's a local IP address and has nothing to do with your cable modem. Even if you had everything disconnected from your router except for your computer you should still be able to get to that.

What does the connection light between your computer and the router show? Cables can go out. I would connect the modem to the uplink connection on the router.

I've had similar problems with my DSL. All of a sudden the internet will go out. Usally I can just go into the router and reconnect but every so often I have to turn off and reset the modem. Very rarely I have to reset the router.

The "Uplink" port shouldn't be your problem, that is used if you want to expand your network with a hub or switch. If your not going to expand your network in this way, make sure the "Uplink" switch is in the "Normal" position. Anything in port 4 (with "Uplink" on) will be seen as a hub or switch and service could be intermittent for that one host. Your modem should be in the "WAN" port.

There should be a reset switch somewhere and in the manual a procedure to reset the router to the factory defaults (Start over).

Unless your running wireless, there should be no need to configure anything, DHCP and NAT should be plug and play unless you want to lock down MAC addresses.

Guy came out, replaced ends on cable at the pole. The DB in the line was 45 and should be in the thirties. Now its 32. The splitter outside was at 0 volts, and now its -4 where it should be.

Said that was the problem, but it wasnt. They're sending out another tech, joy.

I know what the uplink is for, but you dont have to use it for adding hubs/computers. I have a 16 port hub next to my computer that sends the connection off to 4 different computers. Mine, and three servers. Ive tried it with/without the router, with/without my hub, straight modem, one pc, etc. And it still dives.

Resetting the router isnt going to do anything. If it was then all the different routers would have made a difference.

To whomever gave me negative rep points on this post, the least you can do is say why you gave it. The most you can do is actually sign your name to the red candy.

I still stand by the fact that it has nothing to do with the public side of your network if you're talking to a local IP address, unless you have something configured wrong on your router or the router is a piece of trash.

EDIT: Or you can be a baby and give me another piece of red candy with no explanation. Grow some balls. Sorry about doing this on your thread RoD.

The router only locks down when the modem does it. And it cant be on my end after all the testing i have done. By your reasoning it would work flawless with a direct connection to the cable modem and it has the same problem.

RoD, just throwing out ideas to help ya out. I just said that because in your last post you were talking about using the "Uplink" mode and connecting the modem to this port is a waste of time since that's not what it's designed for.

The only thing I can think of is possibly adding a line amp. How many cable connections you have in your house? If it's 5 or more, you probably need one. I had the same problem about 2 years ago, internet would go in and out and at the time I had no router. Put in a line amp down in my family room and havn't had a problem since. You SNR levels should be above 30db and power between -15dBmv and 15dBmv but you don't want it to the extreams.

itsme86, not sure why you got a neg rep because your statement is a fact, you don't need an internet connection to access the router's web interface.

Having thought about itsme68's reply, have you been able to get to the 192.168.1.2 on any of the routers you've tried? If not, it's for sure either a bad router or patch cable. Your internet connection should have no impact on this at all.

The question isn't "Is the cable good", the question is, are you using the right kind of cable? Straight-through, cross-over, roll-over? You shouldn't have any problem access the web application.

Who's the moron giving out the neg reps??? I'm getting sick of this place, no control, people rip on others reps because they can't take critisism, then they rip on ya for trying to help. And they don't have the balls to make a comment.
